PANIC, LANDED ON THE SNOWY GROUND AND STARTED AWAY BUT APPEARED TO BE FINE. OUR ENTIRE AREA IS UNDER A WINTER STORM WARNING THAT GOES INTO EFFECT SOMETIME AFTER MIDNIGHT AND WILL STAY IN EFFECT UNTIL TOMORROW EVENING AT LEAST. THE FIRST FLAKES SHOULD BEGIN SOMEWHERE BETWEEN 3 A.M. AND 5 A.M. IF YOU'RE AROUND BOSTON AND THE COASTLINE, AROUND 5 A.M.. IN HE WHERE IT STARTS WITHIN AN HOUR OR TWO AT THE MOST YOU WILL BE INTO MODERATE TO HEAVY SNOW. IT WON'T END COMPLETELY UNTIL LATE NIGHT, BUT THE HEAVIEST PRECIPITATION WILL FALL AS JUST ABOUT ALL SNOW IN BOSTON AND DOWN TO THE SNOW, PART OF IT WILL. 6:00 A.M. TO 1 P.M. IF IT IS NOT OVER THEN IT WILL CONTINUE TO PRECIPITATE ALL AFTERNOON AND INTO THE EVENING HOURS. WE HAVE A VERY GENTLE WIND THAT IS COLD ENOUGH TO SUPPORT SNOW AND THE TEMPERATURES ARE CHILLY ENOUGH AT THIS TIME. TOMORROW ABOUT MIDAFTERNOON WILL BE THE WARMEST THAT WE GET. INLAND AREAS WON'T EVEN GET TO THE FREEZING MARK. THIS IS A LITTLE BIT WARMER THAN REALITY. IT MAY GET A LITTLE ABOVE FREEZING ON THE SOUTH SHORE AND ESPECIALLY SOUTHEAST MASS AND THE CAKE. BUT BEFORE THIS HAPPENS, WE WILL HAVE TO GO THROUGH SOME MODERATE TO HEAVY SNOW AND SLEET. THAT IS STARTING TO SHOW UP WELL ON THE SATELLITE IMAGERY. IT GOES ALL AWAY FROM KANSAS AND NOW INTO PENNSYLVANIA. IT IS ORGANIZING RIGHT IN HERE. WE HAVE ONE STORM DOWN HERE BUT A SECOND STORM HERE AND THAT IS THE PRECIPITATION THAT WILL MOVE OUR WAY. IF YOU TAKE THIS THE WAY IT'S GOING YOU WILL SEE THE SNOW AREA BUT THIS IS THE SLEET AREA AND THEN THE GREEN IS THE RAIN. THE TIMELINE FOR US AS THIS MAKES ITS MOVE, AND CLEARLY IN OUR DIRECTION, IT GOES LIKE THIS. THE ACCUMULATING SNOW SHOULD BE REACHING WORCESTER BY 5:00 A.M., BOSTON BY 6:00 A.M. I WOULD EXPECTED MORE LIKE 5:00 OR 6:00. THEN YOU SEE THE DARK COLORS HERE. AT 9:00 IT IS SO WIDESPREAD AROUND THE REGION. ALL OF THIS PINK IS SLEET AND IT GETS VERY CLOSE TO BOSTON. IT MAY ACTUALLY GET INTO BOSTON AROUND LUNCHTIME OR EARLY AFTERNOON, THEN IT WILL GO THE OTHER WAY. IT WILL STILL BE PRECIPITATING THROUGH THE EVENING COMMUTE BUT NOT AS HEAVILY AS THE MORNING COMMUTE. HERE IS ONE COMPUTER MODEL THAT HOLDS ON TO THE COLD AIR LONGER AND ALLOWS BOSTON TO BUILD ABOUT NINE INCHES AND WORCESTER 11. EVEN FIVE INCHES AROUND PLYMOUTH. THERE'S ANOTHER ONE THAT SAYS THE SLEET WILL COME IN A LITTLE EARLIER. EVEN AN HOUR OR TWO WILL MAKE A HUGE DIFFERENCE. IT COULD BE A 3-4 INCH DIFFERENCE IN TOTAL ACCUMULATION BASED ON TWO HOURS OF WHEN THE SLEET MOVES IN. MY FEELING IS THAT WE WILL GET TO-FOUR INCHES AROUND THE CAPE BEFORE 3:00 AND THEN RAIN 4:00-6:00 IN BOSTON. NORTH OF THE PIPE I EXPECT 8-12 INCHES OF SNOW AND MAYBE A LITTLE SLEET. MORE ON WHEN THE IMPACT WILL BE GREATEST IN YOUR AREA. WHAT TIME DOES THE SNOW MOVING IN? LET ME SHOW YOU WHAT IS HAPPENING. THIS IS WHAT WE THINK WILL HAPPEN IN BOSTON AND THE SOUTH SHORE. BETWEEN NOW IN 7:00 WE ARE LOOKING FOR A TRACE TO TWO INCHES. IT IS AFTER 7 A.M. THAT THE HEAVY SNOW STARTS TO PUSH INTO THE FORECAST. DOWN FOR THE CAPE, THE CHANGEOVER IS MUCH QUICKER. YOU GET MOST OF YOUR SNOW AT 7 A.M. AND THAT'S ABOUT IT. LIGHT STUFF AS YOU HEAD THROUGH THE AFTERNOON. INLAND IT STAYS AS NO LONGER AND WE WILL BE DEALING WITH SOME SLEET SITUATIONS AS WELL. WE HAVE THAT COLD AIR ALOFT, A LITTLE AREA OF MILD AIR IN BETWEEN. YOU RECOGNIZE THE SLEET BECAUSE IT BOUNCES WHEN IT HITS. IT DOESN'T PILE UP, BUT IT IS VERY SLIPPERY. THIS IS A HEAVY DUTY AMOUNT, NOT SOME OF THE FLUFF WE HAD EARLIER IN THE SEASON. THIS WILL BE MUCH MORE DIFFICULT TO MOVE AROUND. I WANT TO SHOW YOU AGAIN THE AREAS WE ARE TALKING ABOUT. ABOUT 4-6 IN PLYMOUTH THEN SLEET, MAYBE SOME RAIN. THE SOUTH SHORE INCLUDES BOSTON DOWN I-95 TO FOXBORO. NORTH AND WEST OF 128, THAT'S WHERE I EXPECT 8-12 INCHES UP INTO SOUTHERN NEW HAMPSHIRE. HERE IS THE BIG PICTURE. WHAT HAPPENS AFTER THAT? SEVERAL DAYS OF QUIET WEATHER, THAT IS ON THURSDAY, FRIDAY, SATURDAY, AND THE NEXT BIG QUESTION MARK WILL COME IN THAT SUNDAY HAPPENED MONDAY TIME. . IT IS SO EARLY IN THE GAME, IT THERE COULD BE A STORM THAT COMES CLOSER TO US. EITHER WAY WE WILL WATCH SUNDAY INTO MONDAY AS THE NEXT CRITICAL TIME AFTER THIS STORM. RIGHT NOW WE HAVE ENOUGH TO DEAL WITH IN TERMS OF TOMORROW MORNING THROUGH THE MIDDAY HOURS AT LEAST WITH A LOT OF HEAVY SNOW THROUGH THE AREA AND SOME
